Abstract
The base oil production maintaining is the relevant task for brown fields. This is especially important in case of the infill drilling process, due to the fact that infill wells and recompleted wells no only increase conformance factor, but also change distribution of drainage areas. Oil production losses in closely spaced wells might be sufficient, which in turn impact on oil recovery index and the planning of technological development indicators. This article presents the results of interference calculations at the AV1(1-2) object of the Samotlorskoe field, obtained using several methods: regression model, CRM model and reservoir simulation model. In general, all used methods show a fairly high convergence of results. Average percent of base oil production losses are equal to 18,4%. The average share of base oil losses from the production of infill wells is 30%.
